Japanese Cloisonné
The "Golden Age" of Japanese Cloisonné production began in the late Edo period around 1808, and reached its zenith during the Meiji period from 1868 to 1912. During the the late Edo period, Japanese craftsman Tsunekichi Kaji developed a Cloisonné technique called "Yuusen-shippo" that used a delicate filigree wire made of brass, gold, or silver.
The Japanese cloisonné enameling method called Shippo-yaki ("seven precious things"), made use of a fine wire, which was glued rather than soldered to the base metal.Tojima Village (present day Shippo-cho), in Owari Province ( Aichi Prefecture) is famous for the craft of shippo cloisonné.
The Nagoya/Owari area is known for the Owari cloisonné techniques of craftsmen such as Kaji Tsunekichi (1808 to 1883), Hayashi Kodenji (1831 to 1915), . Both Ando Jubei, and Kawade Shibataro introduced the French art of Piqué-à-jour cloisonné into their creations. For the most part early Japanese Cloisonné objects were manufactured for export to Western countries, and the design motifs found in these pieces were influenced by the demands of the western market. "Karakusa" a chinese scroll motif of branches and leaves, was amongst the post popular.
In the late 1800s, a Kyoto crafts, Namikawa Yasuyuki developed "Kyoto shippo" famous for it's use of gilt wire. Owari Cloisonné is known for it's wireless enamelware, a technique developed by Namikawa Sosuke (1847 to 1910) in 1879. The elimination of wire enabled the create elaborate scenic designs that were not possible with wire.
History
Cloisonné first developed in the Near East. It spread to the Byzantine Empire and from there along the Silk Road to China. Chinese cloisonné is probably the most well known and ubiquitous. Russian cloisonné from the Tsarist era is highly prized by collectors. Chinese cloisonné is sometimes confused with Canton enamel, a similar type of enamel work that is painted on freehand and does not utilize partitions to hold the colors separate.
Cloisonné process
Body-making. the artist forms metal (such as copper, bronze, or silver) into the shape of the finished object. The material usually used for making the body is copper, for it is easily hammered and stretched. Filigree-soldering. which is pure silver wire usually about .010 x .040 inches in cross section, is bent into shapes that define the colored areas. The bends are all done at right angles, so that wire does not curve up. This is done with small pliers, tweezers, and custom made jigs. The cloisonné wire pattern may consist of several intricately constructed wire patterns that fit together into a larger design. Solder can be used to join the wires, but it causes the enamel to discolor and form bubbles later on. Instead the base metal is fired with a thin layer of clear enamel. The cloisonné wire is glued to the enamel surface with gum Tragacanth. When the gum Tragacanth has dried the piece is fired again to fuse the cloisonné wire to the clear enamel. The gum Tragacanth burns off leaving no residue. Enamel-filling. The basic elements of enamel are boric acid, saltpetre and alkaline. Due to the difference in the minerals added, the colour differs accordingly. Usually one with much iron will turn grey, with uranium, yellow, with chromium, green, with zinc, white, with bronze, blue, with gold or iodine, red. In time of filling, all the colours, ground beforehand into minute powder and contained in plates, are placed in front of the workers and are then applied to the little compartments separated by filigree. Enamel-firing. This is done by putting the article, with its enamel fillings, to the crucible. The enamel in the little compartment will sink down a bit after firing. That will require a refilling. This process will go on repeatedly until the little compartments are finally filled. Polishing. Some pieces of hard carbon are used for polishing so as to obtain some lustre on the surface of the article. Gilding. The article is placed in fluid of gold or silver. The exposed parts of the filigree and the metal fringes of the article will be smoothly and evenly gilded. The exposed metal is electroplated with a thin film of gold to prevent corrosion and to give a pleasing appearance.
